Wl N D M I L L SPECIFICATION forming part of Letters Patent No. 467,976,dated February 2, 1892.

Application filed October 17, 1891. Serial No. 408,974. (No modelJ Toall whom t may concern:

Be it known that I, FRANK C. Jnconv, of Tulip, Monroe county, Missouri,have invented certain new and useful Improvements in Vindmills, of whichthe following isa full1 clear, and exact description, reference beinghad to the accompanying drawings, forming a part hereof.

My invention relates to machines which are designed to utilizewind-currents for the purpose of generating power for various mechanicalpurposes; and the objects of my invention are to produce a windmillwhich shall be simple, durable, and inexpensive in construction, whichshall utilize the maximum force of wind-pressure, which shall beself-regulating, so as to operate uniformly under varying conditions ofwind velocity, and which shall be capable of being readily thrown intoand out of operation by an attendant whenever so desired.

To the above purposes my invention consists in certain peculiar andnovel features of construction and arrangement, as hereinafter describedand claimed.

'In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-Figure'l is a perspective view of a windmill constructed in accordancewith my invention. Fig. 2 is an irregular horizontal crosssection of thesame on the line 2 2 of Fig. l. Fig. Bis a horizontal cross-section ofthe saine on the line 3 3 of Fig. l. Figs. 4, 5, and 6 are detachedviews of certain details of construction hereinafter described.

In the said drawings, 1 designates the upper part of the tower of myimproved windmill, the said tower being of the usual or any suitable orpreferred type of construction.

2 designates a plate or cap which is bolted or otherwise suit-ablysecured upon the top of the tower 1 and which is preferably of cir cularmarginal contour, as shown.

3 designates a hollow cylindrical casing which is either formedintegrally with the cap or plate 2 or suitably secured thereto, andwhich rises vertically therefrom, preferably about the proportionatedistance shown in Fig. l.

t designates a hollow cylindrical standard or support which extendsvertically through the casing 3, and the lower end of which rests,preferably, upon a horizontal partition or support 5, suitably securedin the upper part of the tower l. The lower part of this supportorstandard et is embraced by a metal band or strap (i, which is boltedor otherwise firmly secured to the adjacent side of a short horizontalbar or beam 7, the said bar or beam thus occupying a position beside thesupport or standard 4 -and a short distance above the upper end of thecasing 3.

S designates a second short horizontal bar or beam which rests upon theupper end of the standard or support el, and to the under side of whichare preferably bolted or otherwise suitably secured two pendentsegmental flanges 9, which partially embrace the upper end of thestandard 4 and thus retain the4 beam or bar S in position upon the upperend of said standard, while permitting said beam or bar to rotatehorizontally upon said standard, for a purpose to be hereinafterdescribed.

11 designates four upright conriectingbars, which are arranged in twopairs, the lower ends of said pairs of bars being bolted or otherwisefirmly secured to the lower horizontal bar or beam 7 at one side thereofand at its extremities. Each pair of these bars 1l diverge upwardly fromeach other to a point about midway of their length and then convergeupwardly, the upper extremities of each pair of bars being bolted orotherwise se cured to two divided bearing-blocks l2, which are thusinterposed between the upper extremities of the bars ll. The upper shorthorizontal bar or beam S is interposed between the two pairs of bars 1lmidway of their length, said bars lying against and being bolted orotherwise suitably secured to opposite sides of the bar or beam S at theends thereof, as shown. Upon the upper side of the horizontal beam orbar `7, at the opposite ends thereof, are bolted or otherwise firmlysecured two bearings 13, through which extends the horizontal shaft 14of the lower wind-wheel l5, to be hereinafter fully deA scribed.

16 designates the shaft of the upper windwheel 17, which will also behereinafter fully described, and this shaft extends horizontally throughthe divided bearings 12, the

wheel17beingin'ounted upon the front end of the shaft 1 6. A't its rearend the lower shaft 14 carries a beveled gear-pinion 18, and at its rearen d the upper shaft 16 carries a similar beveled gear-pinion 19. Thegearpinion 18 of the lower shaft nieshhes vygthV a beveled gear-pinion2O on the lower end of a vertical shaft 21, and the gear-pinion 19 ofthe upper shaft meshes with a beveled gearpinion 22 on the upper end ofsaid vertical shaft 21. This vertical shaft 2K1 is jonrnaled in twobearings 23, which are suitably secu red to the lower and upper parltspfthe reali pail of Vertical bars 11,and said shaft carries two collars24, whiohrestgnpony they upper I Shams @ifl @li und il z see 'es i'et ainalltei n'iore fully explained, the main ha 2,3 is ...Caused t0.rotate. iaxlfilllls' iii lilz'fl prius and. n iis to; bastides/'toedlilaiihelowr ella. i: ile-,lit of the Sllaft 281s 120 bjell'lle @ed 3oby iany sitalileoripreferred gearing with the piiiiip gi @thier machineo r machinery wiiili is to bdi' en byiliewindnill.
